onmouseover selectmenu not working

onmouseover selectmenu not working

Hi everyone!
I want to add onmouseover/hover event to selectmenu, but I'm not able to do it. I think I tried all possible selectors: $(".ui-select"), $("select"), $("div.ui-select"), $(".myselectmenu:parent")..., but without success. Events which I have tried are jquery hover and on({mouseover: function() {...}.., onmouseover in html.

Thank you
